Python is the premier programming language for data science and machine learning, but its native strengths for back-end development can leave developers scrambling for a front-end solution. Enter Streamlit, a robust open-source library for developing front-end applications with Python.

This course is a comprehensive introduction to building Streamlit applications integrated with different Python libraries. You’ll be walked through successive projects to create visualizations, display interactive widgets, and customize layouts. You won’t just display data but work on data transformations using Streamlit interfaces and become familiar with basic functionality for native Python applications like caching and placeholders. You’ll wrap up with deploying your application using the Streamlit cloud.

By the end of this course, you’ll be ready to give your Python-based data science and machine learning applications robust user interfaces using Streamlit.

Building the Frontend of Python Web Applications with Streamlit

First, we’ll load the **Titanic** dataset and manipulate it to meet our requirements.

# Load the DataFrame
We import the dataset and create a DataFrame.

Let’s read the dataset and print it below:

train_df = pd.read_csv("train.csv")
print(train_df)

We need to perform the following operations on our data before our logistic regression model can use it:

* Assign a numerical value to the feature `‘Sex’`.

* Use one-hot encoding on the feature `‘Pclass’`.

* Fill in the missing values in the `age` column.

* Only select the required features.

We’ll define a function to transform our data to make it usable for our logistic regression model.

Learn how to build a logistic regression model on the Titanic dataset.
